SPRING-LEAF LUBRICATOR.

Specification of Letters Patent. Y

Patented June 2v, 1916.

Application filed January 14, 1916. Serial No. 72,023.

To ZZ 'whom t may concern.'

Be it known that I, WILLIAM GBUS, Jr., a citizen of the UnitedStates, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Spring-Leaf Lubricators, of which the following is a specifican tion.

This invention relatesY to the lubrication of automobile spring leaves and the like, and

differs from other constructions for this purpose, by introducing the lubricant from both edges of the leaves. l

llhe principal objectof the invention, is to f provide a novel construction, combination and arrangement of parts for accomplishing this result.

in the drawings-Figure 1, is a side elef ration of a portion of a spring to which a lubricator of this class is attached. Fig.f2,

a sectional view on the line 2-2 of Fig. 1. 3, is a perspectiveof the distributor pan; and Fig. 4 is a perspective of the lubricator pad.

It is found under some conditions, that a more satisfactory lubrication of the leaves of a spring may be'eifected, by introducing the lubricant from both edges of the spring, and the present invention provides a novel and simple construction for accomplishing this result.

In 'the accompanying drawings, a leaf spring of the class to which this invention is applied, comprises a plurality'of leaves 5 of the same size placed one overthe other, so that their edges are in substantial alinement. ;i casing 6, formed with depending sides "i, which'iit closely over the spring and eX- the spring and 1s preferably formed wlth tend below the lower edge thereof. The casis preferably rounded at its edges, so that it fits smoothly over the sprlng, and in each of the depending portions, is a pad 8 of conipressible material, such as felt, leather, or the like, in which a slot 9 is cut for forming a space in communication with a portion of the edges of the leaves within the casing. A perforation 10, is also formed in each pad and corresponding perforations 11, arev provided in the depending portions 7 of the casing, through which a bolt 12, is inserted below the spring with a nut 13 and washer i Ft the threaded end, for binding the pads S litly against the edges of the leaves and for holdin@ the casing on the spring.

A pan lo, is inserted in the casing on top u pstanding edges 16, which are slit in opposite sides forming tongues 17, which extend into the slots 9-of the pads 8. The center of this panY is preferably raised, so that the lubricant deposited therein will flow through the openings into the spaces formed by the slots 9. An oil cup 18, of any suitable construction, is threaded into the top of the casing and communicates directly with the pan 15, so that the lubricant inserted through the oil'cup, falls directly upon the pan 15, and is thereby distributed or diverted to the .edges of the spring, where the lubricant will enten between the leaves by reason of its capillary attraction and the sliding movement of the leaves with respect to each other.

The upper edges of the opposite sides of the pan 15, are preferably bent over at 18, so thatfthey' may be placed above the felt pads 8, thereby holding the pan in place, and preventing it from rattling in the casing 6, since the pads 8, are compressible 'against it. The tongues 17, also serve to keep the slots 9, of the pads 8, open at their upper ends, thereby preventing the space formed by the slots in the pads from becoming clogged.

While I have illustrated and described the preferred form of my invention, I do not desire to be limited to the exact details set forth, but, desire to avail myself of such variations and changes as come within the scope of the appended claims.

I claim 1. The combination with a spring comprising a plurality of leaves, of a casmg eX- tending over the-top and below the bottom at each side thereof, a compressible pad with a slot therein disposed in the casing at each side of the spring forming a space for conlining a body of lubricant against 'a portion of the edges of the spring, a pan at the top of the spring having openings at the sides communicating with a slot in the said pad, fastening means for connecting the lower ends of the casing below the spring and for holding the casing in place, and an oil cup at the top of the casing for discharging the lubricant into the said pan.

" 2. In Ya leaf spring lubricator, the combination with a casing adapted to t over a spring and down over the edges thereof; ineans insertible in either side of the casing to confine a body of lubricant against a portion of the edges of the leaves; and a pan insertible in the casing at the top thereof having overhanging edges engaged between the tops of said means and the easing for holding the pan in position and preventing it from rattling.

8. ln a, leaf spring lubrieator, the combinetion With a, casing adapted to lit over the top of a. spring and down along the sides tlie1eof; pads insertible in the side portions of the easing eacli formed with a slot extending upwardly from the loweimost leaf and in communication With a portion of the edges of the leaves; a pan insertible in the casing having tongues extending into tlie slots of the said pads to hold the slots open and in @@vee et? this geteilt may te @brained for :ave eer-its each, by mdreaefigf;

meme? communication with the said pan; and means for admitting a lubricant through the cas- 15 VLLM Jn.
